Determine if the following statement is true or false. If you believe that the statement is false, briefly explain why you think it is false. Small values of x² imply that the null hypothesis in a chi-squared test is true. Choose the correct answer below. A. The statement is true. B. The statement is false because hypothesis tests do not prove the truth of the null hypothesis. C. The statement is false because the value of x² is not considered when determining whether the null hypothesis is true. D. The statement is false because large values of x² imply that the null hypothesis is true.
A study done in 1997 showed that 4.2% of mothers smoked cigarettes during their pregnancy. An obstetrician feels that this percentage is higher now. To test this, the obstetrician takes a sample of 200 mothers and finds that 10 of them smoked during their pregnancy. Test the obstetrician's claim at the a=0.05 level of significance.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
